<P><STRONG>Function</STRONG>
<P>
Print an Object
according to specified formatting options.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
Error DXPrint(Object o, char *options, ...)<BR>
Error DXPrintV(Object o, char *options, char **components)<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>
In the case of
<TT><STRONG>DXPrint</STRONG></TT>, the arguments following
<TT><STRONG>options</STRONG></TT>
should consist of a
<TT><STRONG>NULL</STRONG></TT>-terminated list of strings.  These strings
specify the components of a Field to which the options should be
applied.  Alternatively, the components may all be specified together
in a
<TT><STRONG>NULL</STRONG></TT>-terminated Array of strings and supplied as
the
<TT><STRONG>components</STRONG></TT>
argument to
<TT><STRONG>DXPrintV</STRONG></TT>.
<P>
If <TT><STRONG>components</STRONG></TT> is not specified or is
<TT><STRONG>NULL</STRONG></TT>, the formatting options are applied to
all components.
<P>
If
<TT><STRONG>
o
</STRONG></TT>
is a Group or other Object capable of containing another
Object, then it is traversed in a depth-first order, and the appropriate
printing options are applied for the particular Object currently
being visited.  If the Object being printed is not a Field, then the
specified component names are ignored.
<P>
The formatting options are:
<UL COMPACT>
<LI>r - Recursively traverse the Object.
<LI>o - Print only the top level of the Object.
<LI>d - Print first and last 25 items in Arrays, as well as headers.
<LI>D - Print all the items in Arrays as well as headers.
<LI>x - Print in expanded form rather than compact form.
<LI><I>n</I> - Print Object to <I>n</I> levels.
</UL>

<P><STRONG>Return Value</STRONG>
<P>
Returns <TT><STRONG>OK</STRONG></TT> or returns <TT><STRONG>NULL</STRONG></TT>
and sets an error code.
